hello,
I have a small computer (AEC 6820 ) with extention for compact flash card . For my navigation computer on my sail I would prefer run Xp and navigation program on flash card instead of HDD ( consumption and shock consideration ) I don't succes to  install Xp on a compact flash card .( the HDD is always seen as Primary master and compact flash card as secondary master ; is there a way to modify that ? ) is it the cause of my problem ?
escuse my poor language :I am french !
thank you for your help
brunoWelcome to the CH FORUMS. There are many aspects to trying to achieve your objective.Google has many articles on the subject. Even you=tube videos.However given your limitations re the English language i have found one that i BELIEVE is able to be followed by someone whose mother tongue is not English. As i SEE it your WISH is not to be able to transfer and install XP to your "navigation computer" but to actually run the O/S from the flash drive on that computer.Please read the following article and pay particular attention to the limitations and cautions that are mentioned (particularly the LAST paragraph).Hope this helps.
